DRUM.

SPECIFICATION forming part of Letters Patent No. 573,320, dated December 15, 1896.

Application filed December' Z7, 1895. Serial No. 573,478. (No model.)

To all 'whom t 71mg/ concern,.-

Be it known that I, EMILE BOULANGER, of the city of St. Louis, State of Missouri, have invented certain new and useful Improvements in Drums, of which the following is a full, clear, and exact description, reference being had to the accompanying drawing, forming a part hereof.

My invention relates to drums; and it consists in the novel construction, combination, and arrangement of partshereinaftershown, described, and claimed.

The figure is a side elevation of a drum, parts being broken away to more clearly illustrate Iny invention.

Illy invention consists, specifically, of applying a device to a drum for arresting the vibrations of the drum-head.

In the drawing, 1 represents the drumshell; 2, the batter-head; 3, the snare-headg 4, the upper rim, and 5 the lower rim; and my vibration-arrester consists of the lever 6, pivoted near its center to the post 7 by means of the pin S, which post is attached to the drum-shell 1 by means of the screw 9.

The lower end of the lever 6 is substantially straight and nearly parallel with the drum-shell 1, while the upper end extends inwardly and upwardly and has upon its upper end the head 10, and upon the upper face of said head is attached a piece of sheepskin 11, with the wool normally in contact with the under side of the battenhead 2 of the drum. Lugs 12 and 13 are attached upon opposite sides of the drumshell 1 and in alinement with each other, and a set-screw 14 is scre\ seated in said lugs and through the shell 1, with its inner end engaging the lower end of the lever 6. The pressure of the woollysurface 11 against the batter-head or 'its position relative to said batter-head is adjusted by manipulating the screw 14. The retractile coil-spring 15 is attached to the extreme lower end of the lever Gand to the innerface of the drumshell 1, and the tension of said spring 15 is normally exerted to hold the lever G in engagement with the inner end of the setscrew 14E and to hold the woolly surface 11 out of engagement with the batter-head 2.

In the practical operation of my invention the set-screw 14: should be loosened until the woolly surface 11 barely touches the batterm head. Then by testing the head and tight ening the screw the vibrations may be regulated to suit the drummer.

I claim- In a device for arresting the vibrations of the head of a drum, a lever pivotally at tached to the drum-shell having the head faced with sheepskin with the wool in con.- tact with the drum-head, a retractile coilspring attached to the opposite end of the lever to hold the woolly surface normally out of contact with the drum-head, and an adj listing-screw penetrating the drum-shell and in contact with the arm of the lever by which the pressure of the woolly surface is regulated relative to' the drum-head, substantially as set forth.

In testimony whereof I aiiix my signature in presence of two witnesses.
